Reference architecture
Local control reliability with plant-wide operational intelligence.
The architecture separates deterministic field control, supervisory operations and enterprise data services. PLC control remains available even when upper-level servers or external interfaces are offline.
L1
Operations & information
Operator stations, alarm management, historian, reports, analytics, mobile access and energy-performance visibility.
L2
Industrial network
Segmented industrial Ethernet, gateway boundaries, diagnostics and secure plant connectivity for FMCS, BMS and EMS data exchange.
L3
Control & integration
PLC sequences, interlocks, duty/standby logic, remote I/O, package-system integration and reusable control templates.
L4
I/O & field devices
Temperature, pressure, flow, level, valves, fans, pumps, meters, drives, starters, DDC and package equipment interfaces.
